VAPOR-BURNER.

SPECIFICATION forming part of Letters Patent No. 270,191, datedJanuary'Q, 1883. Application filed April 10. 1882. (No model.)

To all whom it may concern Be it known that 1, CHARLES A. KOEHLER, acitizen of Bavaria, Germany, residing at Decatur, in the county of Maconand State of Illinois, have invented a new and useful Improvement inVapor-Burners, of which the following is a specification.

My invention relates to a new and useful improvement in Vapor-burners,the object of which is to provided a device by which the cessfullyvaporized and burned, and thus enable them to be used for cooking andheating to avoid the production of smoke and smell, and at the. sametime produce an intense heat with a comparatively small consumption ofoil. I attain these objects by the deviceillustrated in theaccompanyingdrawing, in which-- Figure 1 represents the entire construction bya'transverse vertical section, the several A represents thelower orcombustion chamher, having aheavy base, H,provided with a central tube,G, and isprovidcd with two endless rows of small perforations, e 6, onerow being on a liue'with the bottom of the chamber and one on a linewith the under side of chamber A is conical in form, and has acorresponding conical exterior, as shown. Surmounting this conicalchamber A, and formed of one and the same casting, is a generatingchamberofsomewhat smaller dimensions,having perpendicular sides and anoval top.

' At the leitin the drawing is a continuation of the base H, which formsa round stem, E, which is tapped out to secure the end of thesupply-pipe E. At this point is a projection running parallel with andforming a part of the inclined side wall of the chamber A, within whicha channel, B, is formed, leading to the ber from the supply-pipes E.

G represen ts the screw-jet valve, having a perpendicular stem, 0,provided with a channel, (3. This stem passes up through ahole in thebase H, and its upper end is screwed into the division-wall b, as shown.A small shoulder, a, is formed on the outside of thestem O, which,

when the stem is screwed into the division-wall l), fits tightly againstthe bottom of the base H, and prevents the admission of air. Thehorizontal portion, or that which embraces the jeto and screw D, issimilar to others now in use, as are also the drip-cup l and themannerot' connecting it. i 1

The details having been described, the great advantages gained by thisimprovement are these: The oil or fluid being conducted to the burner inthe usual mannerthrough pipesleading from a reservoir, when it reachesthe point or part indicated by letterE its coursechanges and it isconducted in a new and novel manner to the burning-jet 0. After theburner is once heated in the usual manner, by burning oil or fluid inthe dripcup below, the oil or fluid is quickly generated into gas by theaction of the flame on each of the three parts Viz., the tubes and upperchamber.

It will be obvionsthatthe generating-power ofthe burneris exceedinglystrong. The flame, rising from the jet 0, passes up through the tube Ginto the com bustion-chamberA, and has no means of escape exceptthroughthe two rows of small perforations e 6, so then the flame, beingconfined within the chamber A for a time,

heats the whole frame of the burner and pro= duces the first generationof the oilor fluid into gas in the channel B. From thence itrises andfills the generating-chamber A, within which its temperature is raised.By the more direct action ofthe flame upon the entire outer surface ofthis chamber, which it completely envelope, the gas or vapor thereinpasses down through this tube and it is superheated and expanded to itsfullest capacity, by which means a greater force is imparted to theflame and theintensity of heat materially increased, thus rendering itpracticable touse any of the heavier hydro; carbon oils.

In casting this burner a sandcore is placed in mold to form thechamberA,andisretnoved through the tube G. The upper chamber is alsoformed with a sand core, which is removed through an opening at the top,which is afterward plugged up by a screw, (1, as shown. All of the otherholes and channels are drilled.

I am aware that vapor-burners have been constructed in which the fluidis conducted in a tube passing through two concentric rings 1o paratusand a superheatiug pressure-chamber of flame. the fluid becoming"vaporized during In a vapor-burner for heavy oils, the com- 15 itspassage through said tube, and also that biuatiou of the dome-shapedmixing-chamber in a burner using a Wick and having a vapor- A, providedwith the inclined vapor-supply izing chamber the Vapor has beenconducted tube B, terminating in the superposed vapor- 5 to theburning-point through the hottest part heating pressure-chamber A, withthe vaporof the flame. 1 therefore do not claim such conductingtubeO,extendingllownward from 20 construction, broadly, my inventionconsisting chamber A through chamber A, and provided in means forutilizing the heavier hydrocarbon with jet-orifice, drip-cu p, andregulatin g-valve, oils by providing more efificient vaporizing apasshown and described.
